C#在哪里添加方法 [英] C# where to add a method
问题描述
我刚接触C#-就在一天前开始.我必须做一个包含音乐专辑等的简单C#数据库.我遇到的问题是我不能调用我刚刚做过的方法,有人可以帮助我将此方法包括在main中吗?
I'm fresh to C# - just started a day ago. I have to do a simple C# database consisting of music albums etc. The problem I got is that I can't call a method i just did, can anyone help me to include this method in main?
void addnew()
{
int ID = currid;
string AlbNm;
string Art;
string RelDstring;
int RelD;
string TrAmnstring;
int TrAmn;
string Loc;
int Rat;
int ratswitch;
string ratswitchstring;
Console.Clear();
Console.WriteLine("Podaj nazwe albumu");
AlbNm = Console.ReadLine();
Console.WriteLine("Podaj nazwe wykonawcy");
Art = Console.ReadLine();
Console.WriteLine("Podaj rok wydania");
RelDstring = Console.ReadLine();
bool ifintreld = int.TryParse(RelDstring, out RelD);
bool correctyear = RelD < 2014 && RelD > 1900;
while (ifintreld == false)
{
Console.WriteLine("Podano bledny rok wydania, uzyj liczb calkowitych.");
RelDstring = Console.ReadLine();
}
RelD = Convert.ToInt32(RelDstring);
while (correctyear == false)
{
Console.WriteLine("Podano bledny rok wydania, uzyj daty z zakresu 1900-2014");
RelDstring = Console.ReadLine();
while (ifintreld == false)
{
Console.WriteLine("Podano bledny rok wydania, uzyj liczb calkowitych.");
RelDstring = Console.ReadLine();
}
RelD = Convert.ToInt32(RelDstring);
}
Console.WriteLine("Podaj ilosc utworow");
TrAmnstring = Console.ReadLine();
bool ifinttramn = int.TryParse(TrAmnstring, out TrAmn);
while (ifinttramn == false)
{
Console.WriteLine("Podano bledna liczbe utworow, uzyj liczb calkowitych.");
TrAmnstring = Console.ReadLine();
}
RelD = Convert.ToInt32(RelDstring);
Console.WriteLine("Podaj sciezke do pliku");
Loc = Console.ReadLine();
Console.WriteLine("Podaj ocene [1-5]");
ratswitchstring = Console.ReadLine();
bool ifintrat = int.TryParse(ratswitchstring, out ratswitch);
while (ifintrat == false)
{
Console.WriteLine("Podano bledna ocene, uzyj liczb calkowitych z zakresu 1-5.");
ratswitchstring = Console.ReadLine();
}
ratswitch = Convert.ToInt32(ratswitchstring);
while (ratswitch != 1 || ratswitch != 2 || ratswitch != 3 || ratswitch != 4 || ratswitch != 5)
{
Console.WriteLine("Podano bledna ocene, uzyj liczb calkowitych z zakresu 1-5.");
ratswitchstring = Console.ReadLine();
while (ifintrat == false)

Console.WriteLine("Podano bledna ocene, uzyj liczb calkowitych z zakresu 1-5.");
ratswitchstring = Console.ReadLine();
}
}
Rat = ratswitch;
}
VS为静态主程序中的非静态方法哭泣,但是有了currid和currid ++,它就不可能是静态的(至少我这么认为; p) 谁能告诉我如何在我的控制台应用程序中运行此方法?
VS cries for nonstatic method in static main, but with that currid and currid++ it cannot be static (at least i think so ;p) Can anyone tell me how to run this method in my console app?
推荐答案
我假设所有这些都在单个程序"类中.要解决静态"问题,只需创建该类的实例(或其中的任何类addnew
):
I'm assuming this is all in a single "Program" class. To solve the "static" problem, just create an instance of that class (or whatever class addnew
is in):
var p = new Program();
p.addnew();
可能可以使currid
变为静态;唯一的缺点是currid
变量.由于这只是一种学习练习,所以无论哪种方式都没有关系.
It may work to make currid
static instead; the only drawback is all instances of Program
would use the same currid
variable. Since this is just a learning exercise it doesn't matter either way.
